Summary: linux-cell: Setting GALLIUM_NOCELL causes segfault
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [email protected]
I'm running from the latest version in git (last change @ Wed Mar 4 16:48:51
2009 -0700). I built mesa with 'make linux-cell' (running on a PS3). When I
define GALLIUM_NOCELL=1, every program I run segfaults in
sp_vbuf_allocate_vertices. This is not the case without the environment
variable defined: the programs run fine (of course with graphical issues, but I
understand its still a work in progress). I know it had previously worked, but
before recently, the last time I had updated had been a couple months ago so I
don't know when it broke.
Here is the trace when running bounce (from progs/demos):
Program received signal SIGSEGV, Segmentation fault.

Let me know if there's any other info I can provide to help debug.
